Log Out of Cisco DNA Center

Follow the steps below to log out of the Cisco DNA Center web-based GUI interface.

For security reasons, we recommend that you log out whenever you complete a work session. If you do not log out yourself,
Cisco DNA Center will log you out automatically after 30 minutes of inactivity.

Procedure

Step 1

Click .

Step 2

Click Sign out. This ends your session and logs you out of Cisco DNA Center.

Reconfigure the Appliance Using the Configuration Wizard

If you need to reconfigure a Cisco DNA Center appliance, you must use the Cisco DNA Center Configuration Wizard to update the appliance settings. You cannot use the Linux CLI to do this. The normal Linux administration
procedures that you might use to update configuration settings on a standard Linux server will not work with a Cisco DNA Center appliance, and should not be attempted.

Once the appliance is configured, you cannot use the Configuration Wizard to change all Cisco DNA Center appliance settings. Changes are restricted to the following settings only:

Host IP address of the appliance

DNS server IP addresses

Default gateway IP address

NTP server IP addresses

Cluster Virtual IP address

Static routes

Before you begin

You will need the following:

Secure Shell (SSH) client software.

The IP address that you configured for the 1Gbps CIMC Port (M) on the appliance that needs reconfiguration. To identify this
port, see the rear-panel figure in Front and Rear Panels. You will log into the appliance at this address, on port 2222.

The Linux user name (maglev) and password currently configured on the target appliance.

Procedure

Step 1

Using a Secure Shell (SSH) client, log into the IP address of the CIMC port of the Cisco DNA Center appliance that needs to be reconfigured, on port 2222. For example:

$ ssh maglev@<CIMCPortIP> -p 2222

Step 2

When prompted, enter the Linux Password.

Step 3

Enter the following command to access the Configuration Wizard.

$ sudo maglev-config update

If prompted for the Linux Password, enter it again.

Step 4

The Configuration Wizard will present an abbreviated version of the same series of screens shown in, for example, Configure Add-On Nodes. Make any needed changes to the settings presented. When you are finished making your changes on each screen, choose [Next] as needed to proceed through the Configuration Wizard.

Step 5

At the end of the configuration process, a message appears stating that the Configuration Wizard is now ready to apply your
changes. The following options are available:

[back]—Review and verify your changes.

[cancel]—Discard your changes and exit the Configuration Wizard.

[proceed]—Save your changes and begin applying them.

Enter proceed>> to complete the installation. After entering proceed>>, the Configuration Wizard applies the changes you made.

At the end of the configuration process, a CONFIGURATION SUCCEEDED! message appears.

What to do next

Ensure your changes are applied and active by power-cycling the appliance, as explained in the topic Power-Cycle the Appliance.

Note

If you have updated DNS Server IP addresses, Cisco recommends that you perform a cold boot when power-cycling the appliance.
This will ensure that your DNS changes are applied.

Power-Cycle the Appliance

Whenever you have finished troubleshooting problems with a Cisco DNA Center appliance, you should power-cycle it. The type of power-cycle you perform depends on the type of problem you were solving.
You can perform a warm restart if you have corrected problems with the software, or a cold restart if the problem involved
repairing the appliance hardware. In both cases, any software changes you have made will be applied and active.

Before you begin

You will need the following:

Secure Shell (SSH) client software

The IP address that you configured for the 1Gbps CIMC (M) port on the appliance that needs reconfiguration. To identify this
port, see the rear-panel figure in Front and Rear Panels. Log into the appliance at this address, on port 2222.

The Linux user name (maglev) and password currently configured on the target appliance.

Procedure

Step 1

Using a Secure Shell (SSH) client, log into the IP address of the CIMC Port (M) of the Cisco DNA Center appliance that needs to be reconfigured, on port 2222. For example:

$ ssh maglev@<CIMCPortIP> -p 2222

Step 2

When prompted, enter the Linux Password.

Step 3

Enter the command appropriate for the type of restart you want to perform:

For a cold restart, enter: $ sudo shutdown -h now

For a warm restart, enter: $ sudo shutdown -r now

If prompted for the Linux Password, enter it again.

Step 4

Review the command output as the host shuts down.

Step 5

If you performed a cold restart: Power up the Maglev root process by turning the appliance back on using the front-panel
power button.
